A new measurement of the FRB DM-galaxy cross correlation and a first joint analysis with the kinematic SZ effect
Samuel McCarty, Liam Connor, Kritti Sharma +8
Understanding the distribution of cosmic baryons is crucial for advancing cosmology and galaxy formation. Localized Fast Radio Bursts (FRBs) are a promising new probe of the diffus…
Baryons in the Darkest Sites of the Universe
Kritti Sharma, Vikram Ravi, Dhayaa Anbajagane +9
The pristine underdense patches of the Universe, cosmic voids, are powerful cosmological laboratories, uniquely sensitive to dark energy, modified gravity, and neutrino masses, yet…
Backlighting the Cosmic Web with Fast Radio Bursts: An Anthology of Dispersion Measure Cross-Correlations with Large-Scale Structure and Baryon Tracers
Kritti Sharma, Elisabeth Krause, Vikram Ravi +11
Fast Radio Bursts (FRBs) probe baryons permeating the cosmic web through their dispersion measures (DMs), which encode the integrated electron density along cosmological sightlines…
Signatures of Suppressed Matter Clustering revealed by Fast Radio Bursts
Kritti Sharma, Elisabeth Krause, Vikram Ravi +3
Complex astrophysical processes regulate the growth of galaxies by injecting energy and momentum into their surroundings, redistributing baryons across megaparsec scales. The clust…
Great Walls of Cosmic Baryons in the Northern Sky
Vikram Ravi, Kritti Sharma, Liam Connor
The dispersion measures (DMs) of fast radio bursts (FRBs) encode the total ionized-gas column densities along their sightlines. Most observed FRBs originate at distances where the…
Quantifying the impact of selection effects on FRB DM- relation cosmological inference
Kritti Sharma, Vikram Ravi, Liam Connor +3
Fast Radio Bursts (FRBs) have emerged as powerful probes of baryonic matter in the Universe, offering constraints on cosmological and feedback parameters through their extragalacti…
Probing baryonic feedback and cosmology with 32-point statistic of FRBs and galaxies
Kritti Sharma, Elisabeth Krause, Vikram Ravi +4
The impact of galaxy formation processes on the matter power spectrum is uncertain and may bias cosmological parameters inferred by large-scale structure surveys. Fast Radio Bursts…
A Correlation Between FRB Dispersion Measure and Foreground Large-Scale Structure
Maryam Hussaini, Liam Connor, Ralf M. Konietzka +4
The distribution of baryons in the Universe remains a fundamental open question in astronomy, and the dispersion measure (DM) of Fast Radio Bursts (FRBs) serves as a valuable tool…
A hydrodynamical simulations-based model that connects the FRB DM--redshift relation to suppression of the matter power spectrum via feedback
Kritti Sharma, Elisabeth Krause, Vikram Ravi +3
Understanding the impact of baryonic feedback on the small-scale (Mpc) matter power spectrum is a key astrophysical challenge, and essential for interpreti…
A gas-rich cosmic web revealed by the partitioning of the missing baryons
Liam Connor, Vikram Ravi, Kritti Sharma +17
Approximately half of the Universe's dark matter resides in collapsed halos; significantly less than half of the baryonic matter (protons and neutrons) remains confined to halos. A…
